If you need to install ownCloud on multiple servers, you normally do not want
to set up each instance separately as described in
Database Configuration.
For this reason, ownCloud provides an automatic configuration feature.

To take advantage of this feature, you must create a configuration file, called
../owncloud/config/autoconfig.php, and set the file parameters as required.
You can specify any number of parameters in this file. Any unspecified parameters appear on the “Finish setup” screen when you first launch ownCloud.

The ../owncloud/config/autoconfig.php is automatically removed after the initial configuration has been applied.
